LINE PIN OR FASTENER.

Application led September 3, 1915.

To all whom t may concern Be it known that I, LUTHER F. LEMLEY, a citizen of the United States, residing at Strasburg, in the county of Shenandoah and State of Virginia, have invented new and useful lmprovements in Line Fins or Fasteners, of which the following is a speciiication.

This invention relates to a line pin or fastener, designed for the use of brick layers in striking a level, and one object of the invention is to provide a fastener which will securely hold the end of the line in position, and which pin may be held in place either by inserting it in a joint or arranging it to bear against the brick work.

A further object of the invention is to provide a line pin or fastener which admits of the rapid and convenient clamping and release of the line, and which may be employed without the necessity of entering the pin within a joint, a desirable procedure under many conditions.

rlhe invention consists of the features of construction, combination and arrangement of parts herein fully described and claimed, reference being had to the accompanying drawing in which Figure 1 is a planv view showing the arrangement of the device for clamping a line in position, in which the fastener is arranged to abut against the wall so as to be held in position. Fig. 2 is a similar view showing thedevice held in position by the insertion of the end of the blade within a joint. Fig. 3 is a side elevation of the device detached. Fig. 4 is a vertical longitudinal section of the same, Fig. 5 is a vertical transverse section.

Referring to the drawings, 1 and 2 designate a pair of coperating clamping jaws having toothed surfaces to engage and clamp the line 3. The jaw 1 forms part of a body or plate having at one end a guide loop 4. for the line and at its opposite end a blade or extension 5. This blade or extension is of less width than the body or plate, whereby shoulders 6 at the point of juncture are produced. The jaw 2 is fixed to a yoke or bracket 7 pivoted to the blade and provided with an arm or lever S, whereby the said jaw 2 may be moved out of engagement with the jaw 1 to clamp the ine between them, A spring 9 connects Specification of Letters Patent.

this arm or lever with the body or plate and tends to hold the pivoted jaw 2 in engage ment with the fixed jaw l to clamp the inserted line. By this construction the pivoted jaw may be readily and conveniently controlled to clamp and release the line.

In the use of the device the blade 5 provides a means whereby the fastener' may be secured in place by inserting said blade within a joint in the brick work, and in such use the shoulders G may be employed to catch and hold the line in position. rlhe jaw 2 is provided with an abutment surface 10 adapted to engage against a side of the brick work, whereby the .device may be held in position, under some conditions, under the pull or tension of the line without the neces sity of employing the holding blade 5. The device will thus be found useful under conditions where the fastener can not be inserted within a joint or where it is not desirable to hold it in this manner.

1. A line pin or fastener comprising a stationary aw member having at one end a guide loop and a serrated surface, and having at its opposite end a projecting plate, a movable jaw having a toothed surface for cooperation with the toothed face of the stationary jaw member and having a transverse shoulder arranged at right angles to said projecting plate, a lever having angularly disposed ends, one of said ends being pivoted to the stationary jaw member and fixed to the movable jaw member and the other end of the lever forming a projecting finger piece, and a curved plate spring fastened upon the fixed jaw member engaging said inger piece and operating to normally move said movable jaw member toward the toothed surface of said stationary jaw member, whereby a cord may be held between the jaw members.

2. A device of the character' described comprising an oblong rectangular plate having a guide for the line and a gripping surface or jaw, a pivoted jaw having a cooperating gripping surface and also having a transverse abutment surface arranged in a plane at right angles to said plate, a spring for holding the jaws closed, and a lever pivoted to one of the jaws for operating said jaws.
